Experimentally, the tRNA landscape is complex: different codons … WebJun 17, 2024 · LC/MS can precisely analyze Q-modification in tRNAs, but it is difficult to apply it to tRNA isodecoders at a large scale. Gel electrophoresis methods can quantify Q-modification in individual tRNAs, but still requires micrograms of total RNA and is done for one tRNA species at a time. Neither LC/MS nor gels have sufficient resolution for the ...
